The Email Finder in Ocean.io helps you discover and verify business email addresses with minimal bounce risk.
It searches across multiple trusted data sources and then verifies each result through ZeroBounce, ensuring your outreach stays accurate and deliverable.
Finding Emails
There are two ways to uncover and verify email addresses in Ocean.io - individually or in bulk.
Find Emails Individually
Click the Access email button in the Email column next to a contact, or on the button in the quickview.
Ocean.io will search through several data sources to locate the most likely email address for that contact and automatically verify it.
When the process is complete, the result will appear in the Quick actions column, the Email column and the quickview.
Find Emails in Bulk
Select contacts
In the Results tab, click the checkbox at the top of the list, next to the Score column header, to select all items currently visible on the page.
You can also choose to select a specific number of items at once.
Use bulk selection options
Select all items in your search results
Select a specific number of items (e.g., “Select first 500 results”)
Clear all selections
Open the action bar
After selecting at least one contact, the action bar will appear at the top of the Results tab.
Click “Enrich”
Choose whether you want to enrich these contacts with emails, phone numbers, or both.
Ocean.io will begin searching for and verifying the selected email addresses.
⚠️ The enrichment process may take a few moments depending on the number of contacts selected.
When it’s done, you’ll receive a notification with a link to view all processed contacts and their results.
Any contact that you've already successfully enriched in the past, won't be enriched again. In other words, it's safe to have them in your selection when performing a "bulk selection", as they will just be skipped in the process and won't cost additional credits.
Email Statuses
Ocean.io will display one of several statuses for each contact after the email search is complete:
Access email
You haven’t started the search for this contact yet.
Verified email found
A verified, deliverable email has been found and verified through ZeroBounce - these addresses are safe to use for outreach and should have minimal bounce risk.
Catch-all email found
The domain accepts all emails sent to it. These are generally deliverable but not individually verified.
Guessed email found
An email has been estimated based on patterns or public data. Accuracy may vary, so proceed with caution.
No email address found
In rare cases, no verified, catch-all, or guessed address could be found for a contact.
Filtering for Verified Emails
Once you’ve uncovered and verified emails in your account, you can use the Email status filter to view only those contacts whose email addresses have been confirmed.
To filter for verified emails:
Go to your People search.
Open the Filters panel on the right-hand side.
Open the Email status filter and enable only Verified emails
This filter only applies to email addresses that you’ve already uncovered and verified within your own account.
Using this filter is the best way to prepare clean, high-quality data before exporting your contacts.
Exporting Verified Emails
After filtering for verified results, select the contacts you’d like to export and click Export.
Only emails you’ve verified through your Ocean.io account will be included, helping you maintain the lowest possible bounce rate in your outreach.
How the Email Finder Works
Behind the scenes, the Email Finder combines multiple high-quality data sources to locate each contact’s most likely business email address.
Every result is then passed through ZeroBounce’s verification process to confirm deliverability and accuracy.
This double-layered approach helps Ocean.io keep your bounce rates low and your outreach performance high.
